Slip Stream’s classic, cat-eye styling is reminiscent of a golden age of sunglass design. The frames effortlessly fuse this style with the cutting-edge technology, performance and comfort synonymous with the Cocoons brand. Amethyst Cocoons have a brilliance in their translucent finish. The hand-painted artistry gives the frame incredible depth and distinction while remaining deceptively functional, comfortably accommodating larger eyewear while maintaining a chic, polished look. The dark gray, polarised lens system enhanced with a flash silver mirror coat eliminates harsh glare, blocks 100% of harmful UV light, and is highly scratch-resistant. Each pair includes our legendary Cocoons case, a lens cleaning cloth and the Live Eyewear lifetime warranty. Our handy, machine washable Cocoons lanyards are available for added comfort and convenience (sold separately).
“Marvelous! My friend told me I just had to get some Cocoons and I’m so glad I did. People always comment how they like the colour.”

SILVER MIRROR LENS SYSTEM
One of our most popular lens tints, the classic silver mirror has long been a hit with boaters, skiers, and drivers. It’s the gray lens’s neutral tint that keeps the lens versatile and ready for anything; it offers true colour definition and 100% optical correctness when up against bright light and blinding glare. The mirror coating improves the polarisation efficiency of the lens, further enhancing its effectiveness against glare and bright light.

INCLUDED ACCESSORIES
Every pair of Cocoons includes our world famous Cocoons case. Manufactured from the highest quality neoprene, the Cocoons case is virtually indestructible.

POLARÉ® LENS SYSTEM
Lightwaves reflected from horizontal surfaces produce harsh, penetrating glare that can greatly distort and hinder visual acuity. Polarised lenses act as a chemical “venetian blind” that eliminates blinding glare by neutralising the reflected light before it reaches the eyes. The Polaré lens system delivers maximum polarisation efficiency to enhance visual performance while allowing the eyes to remain relaxed and focused.
Sporadic weather conditions (clear to moderate cloud cover) call for lens tints that effectively decrease light intensity while enhancing contrast and depth perception.
Long sunny days with intense light levels and blinding, reflected surface glare require darker tints and mirrored lens finishes to provide maximum eye comfort and visual performance.
As daylight hours and sunlight intensity begin to decline from summer, contrast-enhancing lenses that feature moderate tints will maximize visual performance and comfort.
Low, flat light (overcast conditions) require high light transmission tints that “brighten” your view while increasing contrast. Activities with intense surface glare call for dark tints with mirror finishes.
